XMP profiles are still seemingly more conservative for DDR4, since I would typically run my 3200MHz DDR4 at 3840MHz. That stopped once I added a couple mismatch

XMP profiles are still seemingly more conservative for DDR4, since I would typically run my 3200MHz DDR4 at 3840MHz. That stopped once I added a couple mismatching sticks though, now I have to run the set at 3105MHz or the system won't POST. Not a particularly big deal.
